1. Simplify the above system block diagram, and determine its closed-loop transfer functions.
for the following questions, given
2. Determine the range of K that will make this unity feedback system stable using Routh-Hurwitz criterion.
3. Given K = 90, draw the Bode plots for the above system, and determine its gain margin and phase margin.
4. Obtain the steady-state error for a unit step input.
Design a Mealy circuit has two inputs, X and Y, and two outputs, Z and W. If the two inputs are 0 at the previous clock rising-edge and then 1 at the next clock rising-edge, then an output Z = 1 (else Z = 0). If one of the inputs is set to 1 and t..
given signal a e^-(10t) and ask to simplify byfactor of 5. you can asssume that the input to the amplifier circuitwill be a corrupted version of this signal: Vin(t)=e^-(10t)+0.4sint(377t)+0.2sin(0.1t)+0.2.
A program has a char variable fruit that has been assigned a value. Write a switch statement that outputs "Apple" if the variable contains lower or upper case 'a', "Banana" if it contains lower or upper case 'b', or "Invalid Input" for any other v..
An hydro-electric station has a turbine of efficiency 86% and a generator of efficiency 92%. The effecitive head of water is 150 m. Calculate the volume of water used when delivering a load of 40 MWfor 6 hours. Water weighs /000 kglm3.
A transmitting antenna has a radiation resistance of 72 ohms, an effective resistance of 8 ohms, a directive gain of 20, and an input power of 100 watts. What is the antenna gain, radiated power, and EIRP
A silicon semiconductor resistor is in the shape of a rectangular bar with a cross sectional area of 1x10-6 cm2 a length of 0.1 cm and is doped with a donor concentration of 5x1016 cm-3. (a) Calculate the resistance of this resistor at 300K.
The Fourier transforms of odd and even functions are very important. The reason is that they are computationally simpler than the Fourier transform. Let x(t) = e-ItI and y(t) = e-tu(t) - etu(-t). a. Plot x(t) and y(t), and determine whether they ar..
The electron and hole concentrations as a function of energy in the conduction band and valence band peak at a particular energy. Consider silicon and assume Ec - EF =0.20 eV. Determine the energy, relatiive to the band edges
how do we determine the direction of current in a multiloop circuit with more than one source of e.m.f?
design a new p-type semiconductor material. Acceptor density is Na=5x1015 cm^-3 and there are no donors are present in the material. The effective densities of states for this material is given as Nv=1.8x10^19cm^-3
Determine which of the machines with the following specifications is realizable with a finite number of states. 1) A machine is to produce an output of 1 whenever the number of 1's in the input sequence exceeds the number of 0's.
A delay function should be created such that each time a new value is to be displayed on the oscilloscope it is followed by the determined time delay such that all data is output via the port at a rate of 2Khz. Change the time delay such that the ..
